Core Responsibilities

Primary Functions

Read and interpret blueprints, shop drawings, cut lists, and specifications to accurately lay out and fabricate wood, metal and composite doors and door components according to tolerance and finish standards.
Precisely measure and mark raw stock and door blanks using tape measures, squares, calipers and digital measuring tools to ensure all dimensions meet job specifications and building code requirements.
Operate panel saws, table saws, CNC routers, shapers, jointers, planers and other woodworking machinery to cut, mill, and profile door parts with consistent accuracy and minimal waste.
Set up and program CNC routers and automated equipment using job files, tooling parameters and nesting software to maximize yield and ensure repeatable, high-quality cuts for custom and production door runs.
Fabricate door cores, rails, stiles and panels, performing joinery operations such as mortise-and-tenon, dowel, spline and biscuit joints to achieve structural integrity and tight fit-up prior to gluing and clamping.
Apply adhesives and mechanical fasteners, assemble door units on assembly tables or clamps, and monitor glue-ups until cures meet production quality standards.
Trim, sand and refine door edges, stiles and faces by hand and machine to remove imperfections, ensure flush joints and prepare surfaces for finishing.
Select, install and adjust door hardware including hinges, locks, closers, thresholds, weatherstripping and panic hardware, ensuring correct mortises, bore holes and clearances for smooth operation.
Perform stain, paint and clear coat application in spray booths or by hand, including prepping surfaces, masking, spray setup, mixing finishes and ensuring uniform coverage and cure times that meet shop standards.
Inspect finished doors for dimensional accuracy, finish quality, hardware fit, and overall workmanship, documenting defects, rework needs and final acceptance criteria before packing.
Package, label and prepare finished doors and components for shipping or jobsite delivery, protecting finishes, aligning packaging with shipping specs and generating packing lists or pallet manifests.
Maintain production logs, time sheets, cut lists and material usage records to support inventory control, job costing and continuous improvement initiatives.
Collaborate with estimators, engineers and production planners to review custom door orders, recommend materials and processes, and identify opportunities to reduce cost without compromising quality.
Troubleshoot machining, tooling and assembly issues by analyzing root causes, adjusting machine setups, replacing worn tooling and escalating complex problems to maintenance or engineering teams.
Follow safety protocols, maintain a clean and organized work area, and conduct pre-shift equipment checks, PPE inspections and lockout/tagout procedures to minimize accidents and comply with OSHA and company safety policies.
Train and mentor junior fabricators and apprentices on best practices for layout, machine operation, joinery and finishing to raise overall team skill level and consistency.
Manage inventory of raw materials, hardware and finishes; place reorders for lumber, veneers, cores, screws, adhesives and coatings to meet production schedules and minimize downtime.
Participate in continuous improvement and lean manufacturing initiatives, suggesting layout changes, tooling upgrades and process standardization to reduce cycle time and scrap rates.
Perform basic welding or metal fabrication tasks for steel or aluminum frames and metal door components, including cutting, grinding, tack welding and preparation for painting or powder coat.
Coordinate with installation teams and field technicians to ensure manufactured doors meet on-site fit and specification needs, providing guidance on field adjustments and documenting any site-specific modifications.
Ensure compliance with applicable building codes, fire ratings, hardware standards, and manufacturer specifications for fire doors, egress doors and specialty commercial door assemblies.
Validate dimensional and physical testing requirements for fire-rated doors, acoustic doors and specialty doors, documenting test results and maintaining traceability records when required.

Secondary Functions

Assist in shop maintenance routines: clean and sharpen saw blades, change router bits, lubricate machine components and report worn or damaged tooling to maintenance.
Support order entry and job tracking by verifying part numbers, finishing options and delivery dates with production planning and customer service teams.
Help develop and update standard operating procedures (SOPs), work instructions and quality checklists for door fabrication processes.
Participate in daily production stand-ups and coordinate with the shipping department to meet daily/weekly delivery targets.
Provide occasional on-site support for complex installations, adjustment of factory hung doors or troubleshooting of field fit issues.
Conduct basic repair and rework on returned or damaged doors to bring products back into compliance for resale or reinstallation.
